摘要： The transmission is for transmitting a reciprocating pedal movement into a rotational movement and comprises a pair of pedals suspended for reciprocating movement, two rotating cam members (29) rotating around respective cam axes (33), each rotating cam member (29) having a peripheral cam surface (31), the rotating cam members (29) being coupled to a rotating member (35) through a respective one-way clutch. Flexible tension members (63) are connecting either pedal to a respective one of the rotating cam members (29), which are eccentric to provide for a gearing ratio between angular movement of the rotating cam member (29) and translational movement of the respective pedal to vary, such that the gearing ratio has a minimum value when the pedal is in an intermediate position between its extended position and its retracted position, and major values when the pedal is in its retracted or extended position.

摘要： This invention relates to an improved lever driven bicycle including a shifting mechanism for controlling a drive ratio between the oscillating lever and the drive wheel. The drive lever arrangement may be located about the front or rear wheels of the bicycle and, when about the rear wheel, may include a sole lever or dual levers. The drive lever arrangement includes a drive lever, a force applicator, a shifting mechanism, and a force converter which together transform the oscillating displacement of the lever to a rotation of the drive wheel. The shifting mechanism includes a slide block located about the lever which engages with the drive lever upon downward motion of the drive lever and controllably slides along the drive lever upon upward motion of the drive lever. The position of the slide block corresponds to a drive ratio between the drive lever and the drive wheel.

摘要： A crank device can produce a large torque without increasing the locus of the crank arm. The crank arm has first and second arms which are longitudinally slidably coupled together through a pinion. The second arm is formed with two sets of rack teeth on both sides of the pinion. The pinion has along its circumference a plurality of teeth which are adapted to alternately come into meshing engagement with the respective sets of rack teeth every time the crank arm makes a half turn in the same direction. Thus, the entire length of the crank arm alternately becomes maximum and minimum every time the crank arm turns by 180.degree.. By applying a driving force to the crank arm when the length of the crank arm is maximum, it is possible to produce a large torque.
摘要翻译：曲柄装置可以产生大的扭矩而不增加曲柄臂的轨迹。曲柄臂具有通过小齿轮纵向可滑动地联接在一起的第一和第二臂。第二臂在小齿轮的两侧形成两组齿条齿。小齿轮沿其周边具有多个齿，每当齿轮在相同的方向上转动半圈时，该齿适于交替地与各组齿条齿啮合。因此，每当曲柄臂转动180°时，曲柄臂的整个长度交替变为最大和最小。当曲柄臂的长度最大时，通过向曲柄臂施加驱动力，可以产生大的转矩。

摘要： This invention relates to push rod apparatus for propelling wheel chairs. Several different embodiments of the invention are disclosed. All the embodiments include a plurality of push rod mechanisms that provide the occupant with a means to propel a wheel chair in a forward and reverse direction. In addition, the push rod mechanisms of the various embodiments all include means to move the push rods away from and toward the center of the rear wheels of the wheel chair to which the push rods have been added. The push rods are extended away from the rear wheels of the wheel chair when in their uppermost position to place the push rods in a better position to be engaged by the occupant of the wheel chair and retract toward the center of the rear wheels in their lowermost position so that the push rods will not contact the surface on which the wheel chair is moving.

摘要： In order to form a largely oval circulatory path, in particular a pedal (1a), a crank drive (1) is described which periodically changes the effective lever length of a crank (2). In this case, gear levers (4′ or 7) are mounted on a crank (2) at both ends (2a, 2b) which rotate in opposite directions with respect to one another and thus form two further movement axes within the pedal path and are thus adapted to the natural human leg movement in a force-saving and ergonomic manner.

摘要： A crank apparatus for a manually powered cycle comprises a crank assembly and a pair of guide devices. The crank assembly includes a shaft, a first crank lever attached to a first end of the shaft and a second crank lever attached to a second end of the shaft. Each crank lever includes a fixed crank lever member attached to the shaft, a movable crank lever member movably attached to the fixed crank lever member and a follower device attached to the movable crank lever member. The pair of guide devices each includes a guide feature defining a non-concentric guide path with respect to a rotational axis of the shaft. The follower device of each one of the crank levers is engaged with the guide feature of a respective one of the guide devices whereby the movable crank lever member of each one of the crank levers moves between a respective retracted position and a respective extended position with respect to the fixed crank lever member when the crank assembly is rotated about the rotational axis of the shaft.

摘要： A variable pedal driving device for a bicycle, the device allowing the bicycle pedals to slide along crankshafts during operation of the device. Each pedal is coupled to a slide pipe slidably mounted on a crankshaft. The slide pipe is in turn connected to an eccentric member mounted on the main shaft of the driving device. When a pedal is driven in a forward direction, the eccentric member causes the pedal to extend out to a maximum distance from the main shaft, for more efficient driving of the bicycle.

摘要： The invention realizes fluent drive without dead points by continuously cging the angle between the levers (13,14) of the pedals (1). The two pedal levers (13,14) are fixed to two separate shafts (15,16) with common axis (3). The driving shaft (18) is eccentric to this axis (3) and the mechanical connection between the driving shaft (18) and the shafts (15,16) of the pedal levers (13,14) is realized by eccentrics (19,20). With this construction the pedals move faster when coming upwards and slower when going downwards, so when the depressed pedal reaches its lowest point, the other one has already passed its highest point.
